To all 'whomy t may concern 1 Be it known that I', FREDERICK A. BERGMAN, a citizen of the United States, re-

siding at Merrick, county 'of Nassau and State of New York, haveinvented 'certain vnew and useful Improvements in Oil Cups,

adjusted positions in such a4 manner as to f prevent displacement of thesetting ofthe needle valve by vibration or by any accidental blows.

Another object is to so construct the means for adjusting the valve thatany desired number of adjustments 'can be had and which adjustments canbe arranged toproduce an accurate predetermined rate o f feed.

A further object is to provide a new and improved constructionof anvautomatic closure for the lling hole of the oil cup.

For the accomplishment of these and such further objects as willhereinafter beapparent to those skilled in the art to which thisappertains, the invention consists in the construction, combination andv'arrangement of parts herein specifically described and illustrated inthe accompanying drawings, wherein is showna preferredk embodiment ofthe invention, but it is to be understood that changes, variations andvmodifications may be resorted to which fall 'within the scope of theclaims hereunto appended.4

l In the drawings forming a portion of this specification: f i

Fig. 1 is a side elevation of an oil cup embodying my invention. t

Fig. 2 is a central section on the line 2-2 vof Fig. 3.

Fig. 3 is a top view, showing thefilling position to close the fillinghole and x Y Fig. 4 is a view similar to Fig. 3', showing the'illinghole closure in open position..

As shown in the drawings, the numeral 10 indicates the usual threadedstem or nipple of the oil cup which is preferably integral with thecylindrical body portion 11 and is provided with a feed conduit 12,termi` position shown in Fig. 3.

portion 11 is slightly flared' outwardly to l provide a bead 15 aboutwhich the cover 16 isl spun or crimped in` such a manner as'to be Xedwith respect to the body portion 11.

The cover 16 is provided with a filling hole 17 anda filling holeclosure 18 is pivotally mounted.` upon the needle valve g stem 19 and isprovided`withk a downwardly depending flange 20 which rests'upon thecov-.er: 16 andV serves to space the ,closure 18 from the cover.v f lPivotally mounted between a pair. of small lugs 21 projecting downwardlyfrom the under face of closure 18, is a 'lever 22 having one of its endsformed Vinto va semispherical plug 23 constructed and arranged to seatwithin the filling hole 17 and' seal the same when the closure isrotated upon itspivot to bring the plug 23 and hole 17 into" alignment.A small leaf spring '.24 isinserted between the lever, 22 and closure'18to normally urge the plug. 23 downwardly and a pin 25 is secured in theother end of lever 22 and projects upwardly throughy a suitable aperturein the closure 18 to,l provide a means'for actuating the lever y22tocausevthe'plug 23 tov be withdrawn from fthe Y.

away as indicated at j f filling hole 17 when .it is desired to `open or1 ings: through which free access may bev had i tofthe filling hole 17when the closure 18 is given a slight rotation `r`in either directionfrom the position shown in Fig. 3. A -pair l' of springs 29, 30 havetheir contiguous 'ends anchored as `at'Bl to the'closure 18 y and their.otherfend's'suitably anchored as at 32 to the fixed cover 16.1soas'to'normally urgeror hold vthe closure`18 in vitsy centralfor closed'v`..The upper face of the' closure 18 is? provided with a plurality ofspaced upwardly yprojecting pins 33,the heights of which areprogressively increased preferably in'. a clockwise direction startingfrom the lower right hand pinshown in Fig.`f3- and -a sleeve 34,'pivotally ymounted 'upon valve stem 19is providedwith a radiallyextend'- `ing arm 35 `which projects' outwardly over the pins 33 and isprovided with a recess 36 adapted to neatly engage over any one of thepins to lock the arm against rotation. The upper end of the sleeve 34 isrecessed as` at 37 to receive a small washer 88 fixed to llO the valvestem 19, which serves to retain the sleeve 34 upon the valve stem.washer 39 is secured upon the valve stem -1'9 within the cylindricalbody 11 and acts as an abutment for one end of a spring 40, encirclingthe valve stem and having its other end in contact with the under faceof cover 16, thus serving to normally urge the valve toward its seat andalso to hold the recess 36 of the arm 35 in engagement with a pin 33when the valve has been adjusted to any of its open positions.

`If desired, a slot may be 'cut into the side wall of the body portion11 to receive a piece of transparent material 41 Vso as to provide -aninspection window and I prefer to use for this purpose one of 'thesynthetic Compositions of m'atte'r such as are used for electricalinsulation's but which `are now 'constructed iin such a manner as to betransparent, impervious to oil, and are not i as frangible as glass. Themanner of securing this transparent material may obviously be varied 'asdesired as long as oil tight joints are secured. Likewise the form ofthe springs and their points of support vmay be varied and also thenumber and'heights of the pins 33.

The operation of the device is as follows, if it is desired to fill thecup with oil the pin 25 is depressed to withdraw the plug 23 from. thefilling hole 17 and the closure 18 is rotated in either directionagainst the action of the springs 29, 30, to bring the one of there-entrant portions 26 or 27 intoalignment with the filling hole. Thespout of an oil can is then inserted into the filling hole and after thecup is filled the oil 'can is Withdrawn and the closure then springsback under the influenceof the springs tothe closed position'shown inFig.` 3, the plug 23 engaging hole 17 and acting as a lstop to check thereturn movement of the closure and to hold it securelyin the positionshown'in Fig. 3.

To set the needle valve to the desired feeding position, the knurledsleeve is raisedl against the action of spring 40 and rotated to causethe recess 36 of arm 35 to engage one ofthe pins 33, thus causing thevalve lltto be raised off its seat `13 to a distance equal to 'theheightof the respective pin. ItI ywill be noted that if itis desired to closethe needle Vvvalve that it is not necessaryto rotate the sleeve '34 andarm 35 back to a certain fixed or starting position as is common withdevices of this character, but that the needle valve wil-lbe closed forany position of the arm 35'between any of the pins 33. If desired,`thetop face of the closure may have As the pins 33 are secured upon theclo- .sure 18, the settingof the needle valve need not be disturbedwhenever the closure is r0 tated for filling the cup. Vhile I have shown'the need-le valve adjusting means as mounted 'upon a rotatable closure,it will be obvious th'atthe pins 33 could be directly mountedupon theupper outer surface of`- 'any oil cup and that any other form of afilling hole yor closure could be used. l The pin 33 nearest to theprojecting pin 25 in l the `'couiit'er 5 clockwise direction Figs.` 3and 4 is preferably of sufficient height to open the needle'valveztoapoint where a substantially free flowof oil from the cupris i allowed.

Having thus described my invention, what I claim as new and desire tosecure by Let-I ters Patent of the United States, is:

1. An loil cup having affixed .cover pro- 1 vided with a fillingh'ole,la closure rotatably mounted on said cover, said yclosure having aplug pivotally mounted thereon adapted to engage within said fillinghole, spr-ing` means to normally urge said plug towards said fillinghole, and means to normally hold said closure ina position yto causesaid plug to engagesaid filling hole, said closure hav# ing va reentrant'profile adapted to expose said filling hole when said cover is rotatedagainst the action of said last named means.

2.` An oil cup having a fixed flat .cover provided with an unobstructedfilling hole,"

a level closure rotatably mounted on said cover and having a dependingflange to provide a space between said closure and said cover, an armpivotally mounted upon said closure within said space, said arm terminating in a plug adapted to engage within and Y seal said filling hole,resilient means contacting with said arm and cover'to normally v urgesaid plug towards said filling hole, a

pin on said arm projecting through said clo'l sure, and a pair-ofvdivergent. springs normally holding said closure in a position in whichthe `plug is engaged with said hole, said closure having `acontourexposing said filling hole when said cover is rotated' against theaction of said springs.

In testimony whereof I have afiixedv my signature. l
